A modulation scheme for use in a digital mobile radio communications system. The modulation scheme uses a four slot time-division multiple access scheme with 12.5 kHz channels. Each 12.5 kHz channel contains plural sub-carriers and each sub-carrier is modulated with a modulation scheme that encodes at least 4 bits per symbol. The modulation scheme can be used in a standalone mobile radio communications system, or in a hybrid mobile radio communications system that also uses standard TETRA modulation schemes.

The present disclosure relates to wireless communications technologies, and in particular, to a network device, user equipment, and a system information transmission method. In embodiments of the present disclosure, for user equipments of different coverage grades within a coverage area of a cell, a network device uses different sending parameters to send pieces of system information. When receiving a piece of system information, user equipment first determines a coverage grade of the user equipment within the cell, and receives, in a receiving manner that matches a sending parameter used by the network device to send the system information at the determined coverage grade to which the user equipment belongs, the system information sent by the network device. The network device uses different sending parameters for different coverage grades. This ensures receipt of pieces of system information by user equipments belonging to different coverage grades.

An apparatus may determine a cyclic prefix (CP) length for a signal for a communication link based on a dynamic indication. The CP length may be determined from a plurality of CP lengths. The apparatus may communicate the signal using the determined CP length. Determining the CP length may be further based on at least one of a modulation and coding scheme, a subcarrier spacing, a service type, a communication link direction, a rank number, a type or a capability of the node, or a number of nodes scheduled in the same transmit time interval. Determining the CP length may include determining a first CP length for a first symbol of a plurality of symbols in the TTI, and determining a second CP length, different than the first CP length, for a second symbol of the plurality of symbols in the TTI. Various additional and alternative aspects are described herein.
